ModelChoiceField。 ID代替名字 [英] ModelChoiceField. ID instead of the name

问题描述

在 send_option （在视图中）变量中，我的 name 名称为 Send 。
我想拥有 ID 的 Send

In send_option (in views) variable I have name of Send. I would like to have ID of Send

该怎么做？谢谢

表格：

class SendOrderForm(forms.Form):
   send_option = forms.ModelChoiceField(queryset=Send.objects.all())

Model ：

class Send(models.Model):
    name = models.CharField(max_length=50)
    price = models.DecimalField(max_digits=5, decimal_places=2)
    time = models.CharField(max_length=150)

视图：

if request.method == 'POST':
        form = SendOrderForm(request.POST)
        if form.is_valid():
            send_option = form.cleaned_data['send_option']

推荐答案

您可以做的是

if request.method == 'POST':
    form = SendOrderForm(request.POST)
    if form.is_valid():
        send_option = form.cleaned_data['send_option'].id

form.cleaned_data ['s end_option'] 将获取对象，并且通过执行 .pk id c>或 .id

form.cleaned_data['send_option'] would get the object, and you can get its id by doing a .pk or .id
